Abstract

Substituted carboxylic acids or carbonyl compounds are manufactured by condensing aliphatic mono-olefines or technical mixtures containing aliphatic with or without aromatic mono-olefines, with substances having a double bond between two carbon atoms conjugated with one or more carboxyl or carbonyl groups, e.g. maleic acid or anhydride, crotonic acid, crotonaldehyde, acrolein or quinone, and recovering the substituted carboxylic acids or carbonyl compounds from the reaction mass. As mono-olefines may be employed amylene, butylene or products containing mono-olefines, e.g. cracking benzine. The temperature of the reaction is usually above 160 DEG C. The products may be used as such or may be converted with other substances into synthetic resins, pharmaceutical preparations, plasticizing means, lacquers or insulating materials. In examples: (1) amylene (produced from fermentation amyl alcohol) is heated in an autoclave to 180 DEG C. with maleic anhydride and the product treated with lye and then precipitated with a mineral acid, e.g. hydrochloric or sulphuric acid, to produce amylene-succinic acid; (2) cracking benzine, e.g. vapour phase cracking benzine is heated in an autoclave to 200 DEG C. with maleic anhydride, the product is treated with lye, and the substituted succinic acid formed is liberated by means of hydrochloric or sulphuric acid; (3) di-isobutylene (obtained by polymerization of isobutylene) is heated in an autoclave to 210 DEG C. with crotonaldehyde, the product is taken up with sodium bisulphite lye and the aldehydes formed liberated by the action of soda solution or dilute sulphuric acid. The Specification as open to inspection under Sect. 91 comprises also the treatment of aromatic mono-olefines (except styrene and indene), e.g. propylenebenzene. This subject-matter does not appear in the Specification as accepted
